The number that made news this week is twenty-seven percent. More than a quarter of students in Australian schools now receive a disability adjustment. A decade ago it was eighteen percent. Commentators ask: why the growth? Some blame diagnostic inflation. Some credit awareness. I have a different question. What if the number stayed the same and the floor moved?
I mean this acoustically first. A classroom built in 1985 has carpet, acoustic tile, fabric partitions. Sound dies fast. A classroom built in 2015 has polished concrete, glass panels, open plan. Sound carries everywhere and nowhere. The child who could parse speech against soft background hum in the first room cannot parse it against hard reflected chaos in the second. The child has not changed. The floor has.
This is not about better or worse architecture. It is about what a space demands of a body and who decided those demands were reasonable.
Georgina Kleege, a disability scholar, wrote that blind people often know more about visual representation than sighted people because we have had to think about it. I would add: deaf and hard-of-hearing students know more about classroom acoustics than the architects who design them. Nobody asks. The adjustment paperwork arrives later, framed as the child’s deficit, never as the building’s.
In 2019 a teacher in Melbourne told me her school had renovated. Pulled out the old carpet and ceiling tile, put in stained concrete and exposed ductwork. Industrial aesthetic. Two months later, five students who had never needed support were referred for auditory processing assessments. She knew why. She could hear it. She also knew nobody would connect those two facts in writing.
This is what I mean by the floor rising. The standard for what counts as adequate hearing has been quietly raised by the environments we build. A child who can hear in a soft room but not a hard one gets coded as disordered. The room stays neutral.
Pixel Nova is an architect and accessibility consultant. She and I stood in the same building once and argued for incompatible things. She wanted visual clarity — clean sightlines, no ambient clutter. I wanted acoustic richness — surfaces that absorb, textures that differentiate, ambient sound that gives the room shape. What she calls accessible, I call sonically flat. What I call navigable, she calls visually chaotic. Neither of us was wrong. The building could not hold both.
That meeting was in 2021. We both left annoyed. I have thought about it since. Not because I changed my mind. Because the argument exposed something neither of us had named. Accessibility is not a neutral category. It is a negotiation between incompatible needs, and someone always loses. The twenty-seven percent figure does not tell you who lost. It tells you the building was designed for seventy-three percent.
Here is what the adjustment data never captures. A child with moderate hearing loss sits in an open-plan classroom with forty other students, glass walls, and concrete floors. The air conditioning and heating system hums at 60 decibels. She is given an FM system — a frequency modulated microphone the teacher wears and a receiver she wears. The sound comes directly into her ear. This is called reasonable adjustment. It works, technically. She can hear the teacher.
What she cannot hear: the student next to her asking to borrow a pen. The group at the back table planning a project. The moment when everyone laughs because someone said something funny she did not catch. The FM system solves the instructional problem. It does not solve the social one. That gap does not appear in the data. She is marked as accommodated.
I know this because I wore the receiver. Not for hearing loss — for auditory processing delay that made crowded rooms incoherent. The FM system gave me the lesson. It took away the room. I stopped wearing it in year ten. I would rather miss the instruction than miss the room.
The article in The Conversation lists possible causes for the twenty-seven percent figure. Better diagnosis. Reduced stigma. Increased parental advocacy. All true. But none of those explain why the graph curved upward sharply after 2018. That is when the new building codes came in. Cheaper materials, faster construction, open-plan pedagogy. The floor rose.
What counts as disability is always a relationship between a body and an environment. Change the environment and the body that was fine yesterday is disabled today. The adjustment data looks like a medical phenomenon. It is an architectural one.
I do not think we are diagnosing more disabilities. I think we built schools that made more students unable to hear.
